Global Sourcing
Trass, Copper, Nickel & Zinc
Alongside our core construction and energy materials, BASE supplies trass and industrial metals through the same vetted partner network, for buyers who need a single point of contact across multiple material lines. These materials are sourced less frequently than our primary product lines, but move through exactly the same verification and documentation process. We'd rather ship a smaller, correctly-specified order of a secondary material than a larger one we haven't verified as thoroughly as our primary product lines.
Trass
A natural pozzolan used as a cement additive and in specialised construction applications. Sourced in the volumes specialised concrete producers actually require, not packaged as a bulk commodity. Volumes are typically smaller and more specialised than our core construction materials, and we size shipments accordingly rather than pushing buyers toward bulk minimums.
Applications
Copper
Sourced for electrical, construction and industrial manufacturing applications. Purity and grade are confirmed against buyer specification before export. Grade documentation follows the same format buyers already receive for our other materials, so there's nothing new to interpret.
Applications
Nickel
Supplied for stainless steel production and alloy manufacturing, sourced through the same audited partner network as our other industrial metals. Available volumes are confirmed against current partner capacity before a contract is agreed, not assumed from historical output.
Applications
Zinc
Sourced for galvanising and alloy applications across industrial buyers. Available in the grades most commonly specified for industrial galvanising. Purity grade is verified independently of what the supplier reports, the same as every other material in our catalogue.
Applications
A smaller catalogue, held to exactly the same standard as our primary materials. Smaller catalogue, same discipline — buyers shouldn't have to choose between the two.
